LUBRICATING DEVICE.

Application filed November 26, 1915.

To all whom it may concern Be it known that I, ROBERT Noon, a subject of the King of Great Britain and Ireland, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification.

This invention relates to lubricating devices for locomotives and the like, and its novelty consists in the construction and adaptation of the parts, as will be more fully hereinafter pointed out.

The invention consists primarily in a simplified form of apparatus in which oil is forced from a reservoir to the parts of the locomotive to be lubricated, by means of a ram moving in harmony with the actuation of some selected moving part of the locomotive, the ram being placed beneath the normal level of the oil in the reservoir so that it is wholly immersed in such oil and the reservoir being filled with oil the introduction of air into the column of oil is avoided.

There are other desirable features of the apparatus which will be enumerated in connection with the description of the parts.

In the drawings, Figure l is a central vertical section through an apparatus embodyin my invention, and Fig. 2 is a side view of a portion of a locomotive showing the manner of connecting the device to its parts. Fig. 3 is an enlarged detail elevation, partly in cross section of a portion of the pump.

In the drawings, is a reservoir of any convenient size and shape provided with a. bottom 11, side walls 12, 12, and a top 13, the latter being provided with a threaded opening adapted to receive a cover or closing plug 14:. Brackets 15, 15 project inwardly from the side walls and serve to support a strainer of usual form indicated at 16.

Secured to or made integral with one of the side walls of the reservoir is a cylinder 17 which extends partly across the body of the apparatus and is open at both ends and is adapted to receive a rod 18. Also secured to or made integral with the opposite wall of the reservoir is a cylinder 19 arranged in line with the cylinder 17 and which extends part way across the body of the ap paratus but so that a considerable space Specification of Letters Patent.

screws indicated at 21, 21, and which barrel has a central oil receiving tube 22 expanded at its outer end to form a chamber 23 containing a valve 24. The barrel has a machine fit within the cylinder, thereby excluding any possible leakage of oil and the screws 2121 may be loosened so as to bodily move the barrel to vary the amount of entrance of the ram hereinafter referred to. The outer end of the barrel is provided with an annular flange 25 internally threaded and adapted to receive a coupling piece 26 provided with a central bore 27 expanded at the end adjacent to the chamber 23 to form an extension 28 of such chamber and adapted to receive a stem 29 of the valve 24 and a retraction spring 29* adapted to restore the valve to place after it has been unseated as is hereinafter de scribed. To this coupling there is shown secured in the usual manner a nipple 30, which in turn is connected to a conduit (not shown) adapted to carry the oil to the place to be lubricated.

At the end of the rod 18 there is provided a ram 30 of such a form that it will fit snugly within the tube 22, and of such a length that when the rod is at the end of its stroke toward the left, the ram will be wholly withdrawn from the tube 22 and the barrel.

Means are provided to impart a reciprocatory motion to the rod and the ram. To that end a supplemental housing, generally indicated at 31, is secured to or made integral with the reservoir casing and contains a cross head 32 secured to the rod and pro vided with a slot 33 adapted to be engaged by a pin 34 carried by a crank 35 mounted on and moving with a shaft 36 supported in suitable hearings in the side of the housing and oscillated by means of a lever 37 and link 38 connected to any selected reciprocating o-r oscillating device on the locomotive, for instance, the member indicated at 39, so that the rod is reciprocated in harmony with the movement of such piece 39.

In use the reservoir is filled with oil by pouring the same through the top opening and allowing it to pass through the strainer 16. This straining takes out some of the mechanical impurities, but others which are too fine for that purpose are allowed to collect by gravity in the lower part of the reservoir, which thus constitutes a sediment chamber. When in use, the level of the oil should be maintained above the level of the two cylindersl? and 19. 'Oiling devices of this general nature are always provided with gage glasses to indicate the oil level at all times and it should be the business of the engineer to watch such gage and see that the oil does not fall'below the desired level.

When therrod is moved toward the left, the ram 30 is completely withdrawn from the tube 22 of the valve and as this tube is below the oil level, it fills with oil, which presses against the valve 24 and tends to unseat such valve against the pressure of the spring 29 and to fill the bore 27 with oil. Y Vhen the rod is moved toward the right, the ram 30 enters the tube 22 and pushes ahead of it the body of oil in the tube, forcing open the valve 24 and pushing the column of oil through the coupling piece 26 and on into the conduit leading to the parts to be lubricated.

As the reverse movement of the ram takes place toward the left, the valve 24 is gradually closed through the action of its spring and the backward movement of the oil in the fitting 26 is prevented. As soon as the ram in its stroke toward the left is completely withdrawn from the tube 22 of the barrel, the oil in the reservoir again fills this tube and when the ram is again moved toward the right a fresh portion of oil is forced past the valve 24 into the coupling 26 and its connected conduit.

As there is no air within the reservoir beneath the oil level and as the tube 22 is below that level, the ram in its movement simply reciprocates in a body of oil. This movement is so simple and so easy that no particular nice fitting of the parts is required and one check valve 24 is amply sufiicient to prevent any backward flow of the oil during the left hand stroke of the ram. The position of the barrel above the bottom of the reservoir is such that'the sediment from the oil will be collected beneath the barrel and the oil will be delivered to the parts to be lubricated substantially free from such impurity.

I claim:

1. lubricating device comprising an oil reservoir, a supplemental housing secured thereto, a partition between the reservoir and housing, a cylinder secured to the partition and extending into the reservoir, a cylinder in the reservoir opposite the partition cylinder, a rod mounted in the partition Goplel of this pat'nt maybe obtained for cylinder and having a ram for the cylinder opposite the partition cylinder, a slotted cross head. secured to and carried by the rod, guideways in the housing for the cross head, a pin in the slot and a crank for moving the pin in the slot to reciprocate the cross head and rod and thereby alternately force the ram into and withdraw it from its cylinder.
